Seven different stars in our galaxy may show signs of being contained within Dyson spheres, megastructures that could be constructed by advanced civilizations to harness radiation energy from stars, ...

The search for alien life takes many forms, from identifying Earth-like planets to scanning for extraterrestrial signals.

Two surveys of millions of stars in our galaxy have revealed mysterious spikes in infrared heat coming from dozens of them. Astronomers say this could be evidence for alien civilisations harnessing ...

The Dyson Sphere concept is a staple of science fiction, from Star Trek to the novels of Larry Niven, and it sounds like a dream come true: a way to harvest almost all of the immense energy output of ...

In 1960, British theoretical physicist Freeman Dyson published a one-page paper in the journal Science that offered perhaps the most hopeful vision ever conceived of humanity’s technological future.

In 1960, physicist Freeman Dyson put forth a paper in Science that changed the way we talked about alien civilizations. In it, Dyson conjectured that a sufficiently advanced civilization would harness ...
